A method and system for communicating audio, video, and/or control signals within a home entertainment system. One or more signals are communicated between an input device and one or more output devices via one or more networks. The output device can include loudspeakers, display devices, and headphones. In some embodiments an output device, for example a center channel loudspeaker, transmits signals to other output devices. For example, the center channel loudspeaker can transmit a combined audio signal and control signal to a remote loudspeaker over a first network and transmit a video signal to a display device over a second network. The display device displays the video signal. The networks can be wireless, wired, infrared, RF, and powerline.

In accordance with embodiments of the present disclosure, a processing circuit may implement an adaptive filter, a first signal injection portion which injects a first additional signal into a first frequency range content source audio signal, and a second signal injection portion which injects a second additional signal into a second frequency range content source audio signal, wherein the first additional signal and the second additional signal are substantially different. The adaptive filter may have a response that generates the antinoise signal from the reference microphone signal to reduce the presence of the ambient audio sounds at the acoustic output, wherein the response of the adaptive filter is shaped in conformity with the reference microphone signal and the error microphone signal by adapting the response of the adaptive filter to minimize the ambient audio sounds in the error microphone signal, wherein the antinoise signal is combined with at least the first frequency range content source audio signal.

Various implementations include loudspeakers and related waveguides. The loudspeakers can include an adjustable waveguide for modifying the coverage pattern of the audio output. In some particular aspects, a loudspeaker includes: a single speaker box with at least one driver; a waveguide having: a pair of opposing walls that are fixed with respect to the at least one driver; and at least one adjustable wall that is adjustable relative to the at least one driver; and at least one fin coupled to the waveguide for accommodating a gap between the pair of opposing walls and the at least one adjustable wall.

Embodiments are directed to a speaker system that contains an array of multiple dispersion drivers that creates an expansive acoustic pattern to playback multi-channel audio content through a standalone speaker. The speaker system comprises an interface receiving stereo audio; an upmixer generating surround sound formatted audio from the stereo audio including one or more height channels; a virtualizer/downmixer component coupled to the upmixer and generating speaker feeds for two or more loudspeaker output sections, configured to play back the stereo audio, wherein each output section is further configured to play its own dedicated stereo audio signals; and a set of drivers each coupled to a respective output section and configured to project sound in at least two different dispersion patterns.

Disclosed are a button sound-emitting apparatus and an electronic device. The button sound-emitting apparatus comprises a cap part, a exciter, and an elastic component; said elastic component is arranged at an edge of the cap part; said exciter is provided in the middle of the cap part; the elastic component is connected to a housing of the electronic device; the exciter is suspended in the housing; the elastic component is configured for providing an elastic restoring force; the exciter is configured to be used for providing a driving force. The button sound-emitting apparatus is simple in structure and eliminates the need to arrange a front acoustic cavity and a sound outlet hole, and ensures good sound performance.

The present invention provides for an apparatus, system, and method for generating a head related audio transfer function in real time. Specifically, the present invention utilizes unique structural components including a tragus structure and an antihelix structure in connection with a microphone in order to communicate the location of a sound in three-dimensional space to a user. The invention also utilizes an audio processor to digitally process the head related audio transfer function.

The portable stereo music playback system of the present invention includes a portable pure stereo music player and stereo earphones. The left and right channels of the player have two or more electronic frequency dividing(crossover) circuits respectively. The audio domain is continuously divided, and each electronic crossover circuit is output independently through a multi-contact connector. The earphone has a left-channel earphone and a right-channel earphone. There are the same number of driver units according to the numbers of electronic crossover circuits in the left and right channels of the player. Each driver (sounding) unit in the left-channel earphone and the right-channel earphone is connected to the player through an independent wire via a multi-contact connector, the left channel driver units and the right channel driver units in the earphone respectively play back the sound of the audio segments corresponding to the electronic crossover circuits of the left and right channels of the player.

User equipment (UE) includes a housing, an audio output module, and a drive module connected to the audio output module. The drive module is configured to drive the audio output module to move along a straight line between a first location and a second location. The first location is inside the housing. The second location is outside the housing. When the audio output module is in an audio output state, the drive module is configured to drive the audio output module to move along the straight line to the second location. When the audio output module exits the audio output state, the drive module is configured to drive the audio output module to move along the straight line to the first location.

A method and system for a headset with internal gimbal, where the headset comprises a headband, a headband, and ear cups coupled to the headband, wherein each ear cup may be coupled to the headband utilizing an internal gimbal. The internal gimbal may comprise a tip that is wider than its base. The tip may be rounded. The headband may comprise headband endcaps at each end of the headband. A headband slide may be coupled to each headband endcap. The headband ear cups may be coupled to the headband via the headband slides.
